Analysis of test questions: the structure that will develop into branches in the future is leaf buds. The following is a schematic diagram of the structure of leaf buds:
In the structure of leaf bud, Ye Yuan base will develop into young leaves, young leaves will develop into leaves, bud axis will develop into stems, and bud primordium will develop into lateral buds in the future. The growing point can make the bud axis elongate continuously, so it can be seen that the branched bud is an undeveloped branch.
